The threaded portion is at an upper end of the container. The top surface includes a flat resilient member. The closure dispenser includes a cylindrical cap. The cap includes counter threads, an elongated horizontally placed distributor tube, an inner cylindrical stopper, and an outer cylindrical stopper. The counter threads are on an inner side of the cap. The counter threads are capable of screw engagement with the threaded portion of the container along threaded joints. The distributor tube is on a top surface of the cap. The distributor tube includes a plurality of upwardly extending nozzles configured to dispense oil from the container. The inner cylindrical stopper is capable of providing leakproof sealing for the oil.

FIELD OF THE INVENTION

The present invention relates to a hair oil applicator. The invention more particularly relates to a container fitted with a closure comprising an applicator that ensures highly uniform application of the oil on to the hair and especially the scalp while eliminating leakage from the screwed on closure threads that is often observed with conventional bottle closures.

BACKGROUND OF THE INVENTION

Oiling of hair is a habit in many countries especially in South Asia. The application of hair oil of vegetable origin like coconut oil is believed to keep the head cool, especially in the hot and humid tropical countries. Further, hair oil is blended with herbal actives that are believed to nourish the hair and provide desired attributes like low breakage, less split ends, shine, low hair fall etc. In more recent times, vegetable oils are blended with synthetic oils like paraffin oils, silicones etc to provide a more light feel, less stickiness and improved conditioning.

Traditionally hair oil is stored in containers from which it is poured out in the cupped palm, rubbed with both palms and applied on to the hair and scalp. Of late, people are less amenable to applying oil using their hands as it requires them to wash their hands with soap after such application. To solve this problem containers fitted with one or more applicator nozzles have been manufactured and sold.

One problem encountered with such containers is the flowback of the residual oil from the nozzles into the container lid portion to cause leakage from the threaded joints. Another problem, especially with containers having multiple applicator nozzles is the uneven flow of oil through the various nozzles.

JP2004321708 A (Kanebo) discloses a comb to apply a liquid to the hair.

U.S. Pat. No. 5,152,305 A (Niv Lundy) discloses a dye applicator which includes a hollow tubular housing with screw-threaded caps on both longitudinal ends thereof. One of the caps includes a centrally located outlet through which a hollow stem of an integrally formed nozzle unit is fitted. A manually actuable piston is provided within the tubular housing and includes an actuator member longitudinally slidable along the length of and external to the tubular housing. To ensure that the piston does not axially rotate within the tubular housing during a longitudinal sliding motion thereof, a protruding track is longitudinally provided on the inner wall of the tubular housing and mates with a corresponding recess of the piston. A liner such as a disposable plastic bag is provided within the tubular housing above the piston for receiving a hair dispensable product therein. The screw-threaded end caps confine the contents of the applicator during use thereof.

The present inventors have been trying to solve the problems associated with hair oil containers. We have now determined a non-obvious solution to at least some of the problems, in the form of a breakoff tab on the closure nozzle along with specific configuration of the inner side of the threaded cap.

It is an object of the present invention to provide for the above benefit of uniform application while ensuring minimal leakage around the threaded joint of the cap and the container body.

It is another object of the present invention to provide for a hair oil applicator that ensures uniform flow of oil and ease of application in an even manner on to the scalp and hair.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a perspective view of the hair oil applicator of the invention with the closure cum dispenser screwed on to the container.

FIG. 2 is a perspective view of the hair oil applicator with the closure cum dispenser unscrewed from the container with the threads on the container and the counter threads on the closure cum dispenser clearly visible.

FIG. 3 is the vertical cross-sectional view of the inner cylindrical stopper and the outer cylindrical stopper on the inside of the cylindrical cap sitting flush against the resilient member and the perimeter of the top surface respectively to ensure the oil does not leak when the closure is in the closed position on the container.

FIG. 4 is cut-away view of the actual model of the bottle where the inner cylindrical stopper and the outer cylindrical stopper (as in FIG. 3) are shown in the respective positions when the closure is in the closed position.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to FIG. 1, the hair oil applicator is shown in the perspective view with the closure cum dispenser (6) in the closed position on the container (1). The container (1) comprises a base (2), upwardly extending walls (3) leading up to a shoulder portion (14). Upward of the shoulder position is closure cum dispenser (6) which comprises the cylindrical cap (7) on which is placed a horizontally placed distributor tube (9) on top of which are upwardly extending nozzles (10). In the present embodiment, the hair oil applicator is shown with 10 nozzles.

Referring to FIG. 2, the closure cum dispenser is shown unscrewed and distant from the container. The upper end of the container contains the threaded portion (4). The top surface of the container comprises a flat resilient member (5). The flat resilient member comprises an upwardly extending breakable tab (11). As can be seen, the cylindrical cap (7) portion of the closure cum dispenser comprises counter threads (8) on the inner side.

Referring to FIG. 3, the vertical cross-sectional view of the closure cum dispenser is depicted. As can be seen, the cylindrical cap comprises two stoppers on the inner side thereof. The inner cylindrical stopper (12) presses against the resilient member (5) when the closure cum dispenser is screwed on to the threaded portion of the container. At the same time, the outer cylindrical stopper (13) is biased against the perimeter of the upper end of the container.

Referring to FIG. 4, a cut out view of the actual model of the closure cum dispenser is shown. As can be seen, the cylindrical cap is screwed tightly on to the threaded portion (4) of the container with the counter threads (8). Like in FIG. 3, the inner cylindrical stopper (12) is shown pressed against the resilient member (5) while the outer cylindrical stopper (13) is biased against the perimeter of the upper end of the container. Also shown in FIG. 4 is the breakable tab (11) and the nozzles (10).

When the hair oil applicator is to be used, the closure cum dispenser (6) is unscrewed from the container (1). The breakable tab (11) is then broken and thrown away. This ensures that the port created (not shown in the figures) on the resilient member (5) is of a uniform size. The uniform size of a port that is created as a result of breaking of the tab ensures that the flow of oil through the port and thereafter out from the nozzles is uniform. This is a significant improvement over prior dispensers where the resilient member had to be manually torn with a knife or a thick pin to create the port. The port thus created was of uneven size and shape thus creating uneven flow of the oil out of the port and into the nozzles. The closure cum dispenser (6) is then tightly screwed back on to the threaded portion (4) on the container (1). As the closure cum dispenser is tightened to the ends of the threads the inner cylindrical stopper (12) is pressed on to the resilient member and the outer cylindrical stopper (13) is biased against the perimeter of the top surface. To dispense the hair oil, the hair oil applicator is inverted with the nozzles (10) placed on the scalp of the person wishing to apply the oil. The container (1) is then squeezed creating a positive pressure on the oil which flows through the port created when the breakable tab was broken, out through the distributor tube (6), into each of the nozzles (10) and on to the desired area of the scalp.

The oil thus applied may then be rubbed on to the scalp and the hair using the nozzles themselves or using the hands or with the use of a comb. After use, the hair oil applicator may then be placed back on its base (2) at a desired place during which time the residual oil from the nozzles flow back through the distributor tube, through the port and back into the container. The inner cylindrical stopper (12) and the outer cylindrical stopper (13) respectively biased against the resilient member and the perimeter of the upper end of the top surface, ensure no space for the oil to leak out of the threads, thereby ensuring leak tightness.
